About this app

The most complete tool to monitor your battery: Shows historical data (%, mA, mW, mV and temperature), calculates estimated run-times and battery aging, helps calibrate battery, and improves your battery run-time by showing your top consuming apps (requires searching your device for all installed apps).

Top consuming apps are achieved by searching all installed apps on your device, this data is not collected and for your eyes only. Privacy Policy

★ Display historical data using customized graphics, fully scrolling and zooming.

★ Show battery information in status bar/notification

★ Display battery data on your home screen using widgets

★ Trigger alarm based on battery information

★ Calculate remaining time while unplugged or charging (AC/USB/Wireless)

★ Calculate actual battery capacity

★ Support multiple removable batteries

★ List top apps used (requires searching your device for all installed apps)

★ Online help accessible from app

★ Lowest battery consumption on the market


★ Special support for Asus Transformer, Padfone, Inno D6000 and HP dual battery devices.

★ Special edge support for Samsung devices

★ Special root only: Limit battery charging on supported devices (highly experimental, disable+reboot in case of charging issue)

Had this app on multiple phones since 2010! Hard to beat a nice line graph with muliple projections to estimate remaining time left. The main point of improvement would be to have better access to the raw mA and mW consumption data to troubleshoot battery drains. The app favors % per hour in the data logs based from the battery percentage and there are too many entries with 0.00%. It's hard to assess the impact of changes from this.

Thanks for using the app. 0% are only visible in recent history where % is not yet changing. File logs contain mA and % side-by-side for further analysis. You can also record at fast-pace interval and display full history by long-pressing history or going in app's monitoring settings.

useful, but every feature not included in the free version, is paid for individually. EA Games is jealous of how many pointless microtransactions this app has. Plus, the app has ads. They're not very intrusive, just a banner at the bottom, but still- not even EA would dare to put ads when every thing you click on brings up a purchase prompt.

Not true at all. You can make a one-time purchase to enable all. Thanks for comparing me to EA which makes millions. This app doesn't pay the bill, not even the electricity used to make it! Only few elements needs purchase, and most are not used by 99% of users! https://xdaforums.com/t/app-4-0-3c-all-in-one-toolbox.2942186/post-89346259

I like the app and have been using it across multiple devices. The latest is a Schok Volt SV55. I'm a little disappointed that the app cannot discern the correct power draw or charge rate in mA from the device. When charging it gives a negative mA rate and positive mA when discharging. However, it redeems itself partially since it uses cumulative data to predict time remaining to use and to charge. This seems based on battery percentage and not the mA rate. Good job 3c. Please fix the mA issue.
